The current monitoring station locations are shown in theYear 5 NPDES Annual Report (Appendix E) submitted to TDEC. See Notes 4 and 5 for new locations of two monitoring stations.

Rainfall can occur in some parts of the city and not others due to prevailing winds, localized thunderstorms, alignment of ridges and valleys, etc.
